Lymphoid hyperplasia is the rapid proliferation of normal lymphocytic cells that resemble lymph tissue which may occur with bacterial or viral infections. [1] The growth is termed hyperplasia which may result in enlargement of various tissue including an organ, or cause a cutaneous lesion .
The latter is a relatively rare form of differentiated thyroid cancer, accounting for only 3-10% of all differentiated thyroid cancers, [7] and was formerly considered a subtype of follicular thyroid cancer. The mitochondrial DNA of Hürthle cell carcinoma contain somatic mutations. [6] Hürthle cell carcinomas consists of at least 75% Hürthle ...
Follicular hyperplasia (FH) is a type of lymphoid hyperplasia and is classified as a lymphadenopathy, which means a disease of the lymph nodes. It is caused by a stimulation of the B cell compartment and by abnormal cell growth of secondary follicles .
Also known as Hashimoto's disease, Hashimoto's thyroiditis is named after Japanese physician Hakaru Hashimoto (1881−1934) of the medical school at Kyushu University, [126] who first described the symptoms of persons with struma lymphomatosa, an intense infiltration of lymphocytes within the thyroid, in 1912 in the German journal called Archiv ...
The mucosa-associated lymphoid tissue (MALT), also called mucosa-associated lymphatic tissue, is a diffuse system of small concentrations of lymphoid tissue found in various submucosal membrane sites of the body, such as the gastrointestinal tract, nasopharynx, thyroid, breast, lung, salivary glands, eye, and skin.
It shows marked hyperplasia of thyroid follicular cells, generally more so than toxic multinodular goitre, forming papillae into the thyroid follicles, and with scalloping of the peripheral colloid. Graves' disease is an autoimmune disorder, in which the body produces antibodies that are specific to a self-protein - the receptor for thyroid ...
Parafollicular cells, also called C cells, are neuroendocrine cells in the thyroid. They are called C cells because the primary function of these cells is to secrete calcitonin. [1] They are located adjacent to the thyroid follicles and reside in the connective tissue. These cells are large and have a pale stain compared with the follicular cells.
A large majority of the thyroid may be removed (subtotal thyroidectomy) to treat the hyperthyroidism of Graves' disease, or to remove a goiter that is unsightly or impinges on vital structures. [citation needed] A complete thyroidectomy of the entire thyroid, including associated lymph nodes, is the preferred treatment for thyroid cancer.
